Instead, an electric engine, containing a supercapacity battery and a micro-jet turbine engine, powers from the rear as it drives almost silently around a test track.... a micro-turbine engine [acts] as an on-board charger and a high-density battery...

Admittedly, it currently delivers only 30 to 50 miles of driving per charge, but it's a promising concept.

Unlike the venerable sparkplug ignition system, which fires just one or at best two sparks right next to the combustion chamber roof, it is possible to ‘aim’ a laser ignition system to ignite the fuel anywhere in the combustion chamber, therefore focusing the beam where the fuel is most concentrated. By using ultra-fast computing to direct the laser, the engine can be run on a much more efficient or ‘leaner’ fuel/air mixture, which would directly cut a car’s carbon emissions. This heightened control also helps overcome the poor cold-start performance of engines running high blends of biofuels.
